fix doc: actual check-context is "test" not "test / test"

verified with `gh pr checks 102` after the first workflow run on this
branch — github collapses the context when workflow name and job name
match. update tests/README.md merge-gate paragraph to use the verbatim
string so the gh-api branch-protection call in the PR body works.

 ## CI merge gate and fixture tiers
 
-**Merge gate (mechanical):** [`.github/workflows/test.yml`](../.github/workflows/test.yml) runs `pytest tests` with `JAVA_CODEBASE_RAG_RUN_HEAVY=0` on every pull request and on every push to `master`. Branch protection on `master` requires the `test / test` status check to pass before merge and disables force-push. Break-glass policy: `enforce_admins: false` so the sole maintainer can bypass for emergency hotfixes — explain the bypass in the merge commit.

 **Iteration subset (convention):** During implementation, authors name a `pytest` file subset inside each per-PR execution prompt (for example in `plans/CURSOR-PROMPTS-*.md`). The repo **[`plan-prompts`](../.cursor/skills/plan-prompts/SKILL.md)** skill (`.cursor/skills/plan-prompts/`) requires a **`## Tests to run (iteration loop)`** section in that scaffold, placed **after Deliverables and before Tests**. Reviewers follow the repo **[`pr-review`](../.cursor/skills/pr-review/SKILL.md)** skill (`.cursor/skills/pr-review/`): pasted subset command + exit code, and a green full-suite CI link once the merge gate from [`plans/PLAN-TEST-SUITE-FAST-LOOP.md`](../plans/PLAN-TEST-SUITE-FAST-LOOP.md) PR-3 exists. Canonical skill sources live under `.cursor/skills/`; you may copy them into `~/.cursor/skills/` if your Cursor setup loads personal skills only. See [`propose/TEST-SUITE-FAST-LOOP-PROPOSE.md`](../propose/TEST-SUITE-FAST-LOOP-PROPOSE.md).
